DUST-COLLECTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 551,216, dated December 10, 1895.

Application filed July 18,1895. Serial No. 556,372. (No model.)

T all whom, it may concern.'

Be it known that I, HIRAM Josnrn Liv/ER- GOOD, a citizen of the Dominion of Canada, residing at Jackson, in the county of Jackson and State of Michigan, have invented a neiv and useful Dust-Collecting Machine, of which the following is a specification.

My invention relates to improvements in a machine receiving dust-laden air from an exhaust-fan, then separating the dust from the air, and collecting the dust. The dust-laden air is first received from the exhaust-fan into a large settling chamber having hanging cloth arresters operating With a traveling' belt, having drags attached thereto for jarring the dust into the conveyor, Which conveys it out of the collector. In this settlingchamber all the heavy particles of dust are caught. Nothing but t-he fine particles of dust ascend up in the arched tubular cloth collectors. Therefore they are relieved of a large percentage of Work. It has been found in practice that the cloth dust-collector chokes up. The meshes of the cloth become stopped up With the fine pulverulent particles of dust. This causes a back pressure on the fan, reducing the efficiency of the fan and the machine the fan is attached to. I have found the pulverulent dust adhering to the outside of the cloth has the first tendency to stop up the meshes of the cloth. To remove this outside pulverulent dust from t-he cloth dust-collector I have designed and arranged a series of vertically-reciprocating traveling soft brushes, operating in conjunction with the vertical round arched cloth tubes, which have a positive motion, traveling up and down the surface of the cloth tubes, keeping the outside of the cloth clean and crinkling the cloth tubes in such a Way that should there be any iiakes of dust sticking to the inside they Will be loosened and forced down out of the tubes into the settling-chamber below. I have designed a simple Way of securing the arched tubular cloth collectors to the top of the settling-chamber to permit easy removal for repairs. I attain these objects bythe mechanism illustrated in the accompanying dra-W.- ings, in Which- Figure l is a vertical longitudinal section of the entire machine. Fig. 2 is a transverse sectional view.

Fig. 3 is a plan top view of the dec-k, to which are fastened the arched tubular cloth collectors by means of the metal plates 2. Fig. 4 is a sectional view showing the hem or loop on the ends of the cloth tubes, also the Wire inserted in the hem, the metal plate resting on the Wire hoop surrounding the cloth tube and fastened to the top side of the deck'. Fig. 5 is a plan top view of one of the belts with the reciprocating attachment fastened to the belt and which includes one end of t-he pitman journaled on the projecting pin G, the other end of the pitman being attached to the parallel brush-bars, this making the connection between the belts, pitmen, and brush-bars. Fig. 6 is a detail elevation of one of the dust-arresters, showing the frame and cloth.

Similar letters and figures refer to similar parts throughout the several views.

A is the base of the machine, Which consists of a settling chamber. Arranged in this chamber are the dust-arresters N and the travelingbelt M, having the drags L attached thereto, which performs two functions. As the drags L pass along, they come in contact With the lower edge of each of the dust-arresters N and cause the lower edge to go with the belt a certain distance. It then slips off the drags and flies back and strikes the stop O, fastened to the sides of the box A. This jars the dust off thearresters N. It then falls to the bottom of the settling-chamber and is caught by the drags L and delivered to the conveyer K, which delivers the dust out of the collector. The cross-supports S may be fastened to the sides of the box A, or may be fastened to the under side of the deck I3, but preferably to the sides of the box A. To these supports S are attached the flat steel springs R, which carry the dust-arresters N, composed of a coarse open-cloth material. These arresters are arranged in the settling-chamber A for the purpose of forming eddies and arresting all the dust possible in the settling-chamber.

B is the deck or top cover of the box A, perforated full of holes. Over these holes are secured the arched tubular cloth collec tors T. These tubes have a hem or loop made on each end. I then slip over the cloth tube T two metal plates 2 and then insert in the hem the Wire hoop 3. The metal plates 2 are now IOO fastened to the ltop of' the deck B 'by :screws or othermeansof fastening. Thedust-laden air passes up into the arched tubular cloth collect-ors T,vwhich are held up in a perpendicular position by the semioval cross-pieces l1, resting on the-,plates D. As the dustladen air is forced in at one end of the collector bythe exhaust-fan, as shown in Fig. l, the air laden with dust strikes the arresters N, which separate the heavy particles of dust from the air. The air and light particles of dust ascend upward in the Aarched tubular cloth collectors T, which make -a separation of the light dust from the air, the air passing out through the meshes of the cloth tubes T pure and free from dust. The cloth tubes T, formingV the arch at the top gives a continuous course to the air, so that as soon as the flakes on the inside of the cloth tubes T are loosened by the brushes P pressing against the surface of the cloth tubes T', traveling up and down them on the outside, the dust is forced domi out of the' tubes'T into the settling-chamber A.

lE secured on their outer ends.

C represents four upright posts, one placed on each corner resting on the deck B, carryying at the top end the plates I), on which rest the standards XV. Journaled in these standards are the shafts V, which have the wheels Fastened to the deck B, or, may be, fastened to the post C, are the two brackets U, having projecting journals. `Mounted on these journals are the Wheels F. Over these wheels E and F pass the belts 5. There are four of these belts, one on each corner of the machine. By this means the brush-bars Q are raised and lowered parof power.

'Y in Figs. l and 2, it will be seen that the brushes 5o P have a positive up-and-down motion. l

Z is the driving-pulley by which the machine.

will receive its motion from any given source The shaft X has three pulleys on it-the driving-pulley Z, pulley I, and the pulley which the belt 7 passes around and uparound 'the pulley G on one of the shaftsV,`which "has four pulleys on it. 'It will be seen that belt 7 gives motion to shaft V and a belt l0,

passing around pulleys 11, which gives motion to the other shaft V. These two shafts, having the pulleys E on their outward ends, give motion to the belts 5, which givesa positive to the conveyer K, delivering the dust out of the machine.

Having now described the operation of my dust-collector, I am aware that prior to my l therefore do not claim such, broadly; `but What I do claim as-my invention, and desire to secure by Letters Patent, is

1.
